Descriptions

Multiple Cross-Site Request Forgery (CSRF) vulnerabilities in Booking Ultra Pro plugin <= 1.1.4 at WordPress.

Múltiples vulnerabilidades de tipo Cross-Site Request Forgery (CSRF) en el plugin Booking Ultra Pro versiones anteriores a 1.1.4 incluyéndola, en WordPress

The Booking Ultra Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several parameters in versions up to, and including, 1.1.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This can also be exploited via CSRF.
